Maintain system integrity and prevent thermal expansion damage with the Bell & Gossett 1BN360LF, a robust ASME-rated expansion tank designed for precision domestic water applications. Known in the field as model PTA-449, this vessel is engineered to reliably absorb volumetric changes in heated water, effectively stabilizing system pressure and extending the lifespan of your plumbing infrastructure.
The tank utilizes a sophisticated internal design featuring a high-quality FDA-approved polypropylene liner paired with a heavy-duty butyl diaphragm. This mechanism creates a complete physical barrier between the system water and the steel shell, ensuring that the water remains isolated from metallic contact to prevent contamination while maintaining consistent pressure regulation.
Key System Performance Baselines:
- Pressure Management: ASME-constructed vessel designed to handle significant expansion forces safely.
- Water Purity: FDA-approved polypropylene liner ensures clean water isolation.
- Robust Barrier: Heavy-duty butyl diaphragm separates system fluid from the durable steel shell.
⚠️ Application Profile: Ideal for commercial and residential domestic water systems, hydronic heating loops requiring potable compatibility, and thermal expansion control in tankless or storage water heater setups.
